Provide Example for use outside of Rails

[falsetto]

Is it possible to use read_from_slave in a standalone environment? I'm trying the following without success (all reads, even inside of with_primary_slave go to the master). I'm using activerecord 3.1.3 and read_from_slave 0.5.2.

config/database.yml

adapter: mysql
database: master
username: asdf
password: asdf
host: xxx.xxx.xxx.xxx
port: 3306
slaves:
  primary_slave:  slave_for_reads

slave_for_reads:
  adapter: mysql
  database: slave
  username: asdf
  password: asdf
  host: xxx.xxx.xxx.xxx
  port: 3306

example code

require 'rubygems'
require 'active_record'

db_config = YAML::load(File.open(File.join(File.dirname(__FILE__),'config','database.yml')))
ActiveRecord::Base.establish_connection(db_config)
require 'read_from_slave'

class Member < ActiveRecord::Base; end

# Queries master instead of slave
Member.first
# Also queries master instead of slave
ActiveRecord::Base.with_primary_slave do
  Member.first
end
